and similar material, Yandv particularly -tojimprovements in what is kno'wnfas a book-style carton.l

It isthe 'principal object of' this invention to provide a book-style carton or box in which the halves of the boxv are provided with hollow,"

spaced-apart Walls.

Another object of the invention is the provision-,of a box or carton as set forth above in" which the rmain portion of the same is formed from a single blank appropriately cut and scored.

Another object of this invention is the provision of a book-style carton which has an extremely rigid construction, Wherefore'it may be used for display purposes as Well as shipping purposes without the use of an additional 'shipping carton. Y

A further object of'thisinvention is to provide a book-style carton or box that is shipped to the user in a knock-down position, thereby saving on shippingspace ,while the user is provided with a carton which', when set up, has theappea-rance of a rigid set-up box. i

It is also an object of this inventionto j' folded onitself asgthe blank is'. arranged before a knock-down book-style box which can be readily set up by the user Without the use of setting vup machinery or expensive box making experienced' labor.

It is also an object of this inventionto provide a book-style box or 'carton in which the general appearance of such a'packageV has ,been materially improved.v f f Y Other objects and Vadvantages of the present linvention should be readily apparent byreference to the following` specification, considered inv con- .junction with the accomp anying drawings form- Fig. 2 is an extended plan view of a blank which Vforms one Wall ofthe rlnal assemblyof the box of Fig. 1.

Inorderto complete the assembly-of the icar- `ton, the blank is' folded on`the main or. central fold or hinge line 30 with the panels. 38 `on Veach side thereof parallel in back to back position.

lThe extensions 43 are then raised to -have their inner'and outer wall members 41.. and 49 normal to the base V33. The blank 88 setup as'iseen in Fig. 3 is then Vplaced one` on each side of the panels 38 andwith their outer wallvmember in contactfwith. the inner face of their respective panel 38; r.'Ihe end-'wall `extensions 68 and69 of each portion is then folded by causing theirend 4walls outer members 13 to be normal to the bottom panel 33.' This will causef the corner members 4|, 42, 53, and 54 5to be folded on themselves on their score or foldline'81V and Yto be transversely f of the panel 33 towardr the center thereof. The said extensions68 and 69 are thenfoldedon their score line 10,to;dispose thetoppanel14 parallel with the bottom panelv 33, whereupon the end spacer aps 83 anclA 84 are folded .normal to* the inner end wall member 15`and at the', same time the lower spacer flap 16 is likewise folded-Ato be normal to the inner end wallpanel 15. 3' The inner end wall panel is then folded into the vcarton to be normal to thebottom panel 33. vThe end wall extensions 68 and 69 are retained in their folded position by having.; their locking lugs 85 and 86 to respectively engage the adjacent slit |01 and |00 ofthe removableinner hollow wall and .the'adjacentslit l66 andr61of the inner side wall member 149. z.

I The intermediate compartment is formed from the blank illustrated in Fig.- 21,`and is independentlyset up kasin Figs. 22 and23, but being connected with the Ablank |14.' The ,blankf-2I5 inFig.v 1'7 comprises a central panel `2|6 Awhich forms the 1bottom of theintermediate ,compartment andA has connected to its opposite sides through fold lines 2|1 and-2|8similarfex'- tensions 2 9 `and 227|).v Each extension is provided With-parallel scorelines 220, 122| and 222, thereby providing between thescore line 2I8-or 2|1 and .the end ofvfblankppanelsv223, 224, f225 and 226. yThe said panels :are to be folded normal tolo'ne another, thereby providing side Walls of hollow 'or angular cross-section, and in which the panel 223- constitutes the outer Wall-member, the panel 2;4thetop -Wall member, the panel 225 the innerlwall member, .andthe panel 22 6 the glue flap for securing thel inner Wall member to the bottom ,6,after having had applied rto itglue or the like 22.1.:

` The-outer Wall member panels 223 have their vends defined by score o r-fold lines 228and22'9 which respectively-v, hingedly 'connectgthereto tucking naps-23o and 23|. The mening flaps v230 and 23| are attached tobe interlocked with one another Athrough' locking notches 232 and 233 respectively inthe flaps 23D and 23|.

nected to it throughv the score o r fold line 234 a .spacer flap 235 which is enclosedby the interymediate compartment end wall members formed by the extensionsI |80 andl8| of blank-|14.A

. To assemble; the carton the two main sections are erected from'the blank |14 and setup as 'fully Y disclosed in the .upper partof Fig. 19. l That is,

the side walls are raised from their flat to their ,upstanding position, whereupon the end wall extensions 68 and 69 are folded to their position causing the locking tabs 85 and 86 to enter` the slits o f the inner wall members. The blank 2I5 of Fig. 17 is then erected as illustratedv at the upper end of Fig. 22, namely, by raising its side Vwalls from their flat to their upstanding position and interengaging the tucking flaps 230 and 23| and folding the spaced flap 235 to lie parallel with theintermediate compartment bottom 2 |6. The assembled intermediate compartment is then placed on the panel of blank |14 as illustrated in Fig. 19, and the -extensions |80 and |8I of this panel are then folded over the spacer flap 34as illustrated clearly at the right-hand side Vof Fig. 9 to cause the locking flaps Y|93 and |94 of said extensions to enter locking slits 236 and 231 of the inner wall members 225 of the intermediate compartment. f

.; The above results in a carton setup as illustrated in the upper end of Fig. 19,-and as clearly 4 Olle O f, *said flaps, 23| for example, has 4hingedly con- .spacer ap 64.

'50. stead of being separatedfrom the top'wall 48 by -top wall members of each compartment boundsigned to .contact'the upper Wall 'member of the` .bounding IWalls' of said.l intermediate compartment.

nach of the planks above described shows the tucking flaps or corner members such as 53 in Fig. 1 as detached from the'tucking iiap 60 and spacing flap is supported not-only-at one side, namely, at its top .bythe tucking nap 6D, but is also supported by the tucking iiap 53., This construction comprises the connection of the tucking flap or corner piece 53a through a score or fold line 238 with the .adjacent end of the spacer nap 64a, the spacer ap 64a being connected by the score or foldrline 52 'with theftucking flap The inner endv ofthe spacing flap 64 ina`cut line 55, has a portion thereof removedas at 239. In addition, the tucking flap 60 is provided with acut or score line 240 which extends from the outer end of the cutout 239.

The set up of the parts as illustrated in Fig. 24 and just described, is asin Fig'. 25, wherein the tucking flap 60a is disposed 4across the` end of the wall assembly and Ythen folded 'on the score* 01' fold line 24|] to'be parallel With the inner endvvall member. At the Vsaine timethe tucking flap or corner piece' 53ais folded on itself to lie'between the tucking flap 60d and end.

the remainder of the tucking fiap'a andits outer end supported by the tucking flap 53a. In other words, this construction constitutes or forms a bridge for the spacing flap 54a instead of having the spacing iiap merely projecting between the inner and outer foldalble end wal-l members. At the same time the operation of folding the tucking flaptdv tc'be .parallel with the bottom or main panel is eliminated.

It will be understood that the construction illustrated in Figs. 24 and 25 Will be substituted at each corner of the main panels of each section of the carton, namely, the corner members 53 and 54 of the blanks illustrated in Figs. 1, 12,

` and 16 and the corner members .202, 263,21 and 2 2 of the blank illustrated in Fig. 16.

In each of the foregoing cartons each of the four walls of each section is illustrated as having a cross-section of appreciable width and a top wall member of a width equal to the Width of the wall. K In the vpractice of the inventor this is not absolutely necessary Yas the walls, or certain of them: may be made of a double thickness only as illustrated inFigs. 26 to 31 inclusive.

In order to eifect this change the end walls, formed from the extensions 68 and 69, are

'slightly modified as villustrated in the blank of Fig. 26. This modified blank consists in making the extension 68a -of'but two panels 24| and 242 hingedly connected to one another by a hinge or fold line 243. The panel 24| forms the outer Wall member While the panel 242 lforms the inner wall member. In order to khold the Walls in their erected position the inner Wall member has at its outer ends locking tabsy to cooperate with the slits in the adjacent side wall inner Wall members. A

The carton sets up substantially as the cartons In Figs. v2li and 25 a modicaltion of this corner is illustrated, 'Whe'reby the f of merely double thickness and not of appreciable'width. Accordinglythe extension I lla'is `provided with two panels 244 and 245 connected with one another through a hinge or fold line 246. 'I he said panels 244 and 245 form the in'- ner and outer Wall members for the third compartment andare adaptedto enfold the tu'cking 230 and 23j of the blank 215 with. the said tuckingiap. 2,31! having removed from it theA spacer The carton formed fromthe blank of Fig. 29

sets up in the samermanner as that formed from the blank.of Fig. 16 except that end walls ofthe central compartment are of double thickness only instead of appreciable width. Y

FromV the foregoing it is believed nowA evident that there has been provided a book-style carton which accomplishes the objects initially'set forth.

What is claimedV is: c y
